Abstract
【解決手段】 一対の端子電極を有する基板と、該基板上に実装された発光ダイオード素子と、該発光ダイオード素子を被覆する透光性封止樹脂と、基板上に形成された枠体とを有する発光ダイオードにおいて、基板の一対の端子電極のそれぞれの近傍に設ける貫通穴と、枠体の貫通穴に対応する位置に設ける凹部と、該凹部と基板との間に配置される径大部及び貫通穴に挿通配置される径小部からなる導電性弾性部材とを有し、該導電性弾性部材は径大部が端子電極と電気的に接続されていると共に、径大部側の端部が凹部の底部に当接され、径小部側の端部が貫通穴の外側に突出して配置されていることを特徴とする。

Description
前記蛍光材は、発光ダイオード素子20からの発光エネルギによって励起され短波長の可視光を長波長の可視光に変換するものであり、例えばイットリウム化合物等の蛍光物質が用いられる。
本発明の目的は上記従来技術における課題を解決して発光ダイオードが携帯電話等の補助光源として搭載される場合に、筐体デザイン(特に厚み)に柔軟に対応し、簡単な構成により、容易に且つ低コストで実装できる発光ダイオードを提供することにある。また、実装工程において、高温のリフロー工程を無くすことで、透光性封止樹脂と基板との界面剥離を防止し、信頼性や、長期安定性を向上させた発光ダイオードを提供することにある。
また、導電性弾性部材における径大部と径小部とを別体とし、それぞれ独立した部材とすることによって、発光ダイオードを組立後に径小部を基板の貫通穴から挿入することができ、搭載される筐体デザイン(特に厚み)に合わせてその長さを自由に設定することができる。
次に反射枠25を基板22に押圧する。この時、基板22と反射枠25とが、互いに当接する部分で接着材39によって接着され固定される。これによって、図15に示すように、第1のコイルバネ65が圧縮され、その他端65bが基板22の端子電極であるカソード電極23に当接し、押圧され機械的接触により電気的に接続される。
